Ques 6 - 13 p12 answers 6 The rows in the periodic table are called periods. 7 Groups are the vertical columns in the periodic table. 8 Three special blocks with no normal group numbers are the transition elements, the lanthanides and the actinides. 9 There are far more metals than non-metals in the periodic table. 10 The metalloids are: boron, silicon, germanium, arsenic, antinomy, tellurium, polonium and astatine. 11 The non-metals are: H, He, C, N, O, F, Ne, P, S, Cl, Ar, Se, Br, Kr, I, Xe and Rn. 12 Examples might be: iron, gold, copper, silver, zinc, mercury and platinum. 13 a False: Horizontal rows in the periodic table are periods. b False: Vertical columns are called groups. c False: The most reactive metallic atom would be francium Fr. d True: The most reactive non-metallic atom would be fluorine F. e True: The transition elements are all metals.
